Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

past firefox 150 Drag-and-drop for graphics is no longer working; instead of the graphic itself, the graphic's link appears at the destination.

I Admin from Community marvin-und-lisa.de Several users have complained that they can no longer play certain games in my community, because the images can no longer be loaded; instead of the image itself, the HTTPS address of the image appears.

The new Firefox Home layout wastes screen space and pushes shortcut rows lower on the page. Please provide an option to restore the previous compact layout or remove the oversized centered Firefox logo. Productivity users need density and customization, not extra empty space.

I have to reduce the screen page size down to 67% to see the entire screen.

Hello Firefox Team,

I am writing to formally request the development and release of an official Firefox browser version optimized for OpenHarmony / HarmonyOS.

I am currently using a new smartphone running OpenHarmony 6.0. As the ecosystem grows rapidly, there is a substantial and increasing base of users who rely on this operating system for their daily stage environment. Currently, the browser options available on this platform are quite limited.

Firefox is widely celebrated for its privacy-focused features, strong extension/add-on ecosystem, and its independent Gecko rendering engine. Having Firefox natively available on OpenHarmony would significantly enhance the browsing experience, privacy security, and freedom of choice for millions of users within this new ecosystem.

Could the development team please consider adding OpenHarmony support to the official roadmap? Alternatively, if there is an existing experimental build, a community port, or a workaround to compile it for this architecture, I would greatly appreciate any guidance.

Thank you for your time, dedication to the open web, and consideration of this request!

Best regards

Firefox is using disproportionate amount of cpu and memory after upgrade of win 11. How do I fix this. I have an I9 Processor with lots or ram and ssd drives way out of line..

Google has added some AI 'ads' to their title page? This just appeared a day or so ago on my system. How did I remove it, block it? Attached is an image of what I am asking about. What is interesting is in Chrome I can explicitly turn this junk off. But when using the Google search title page with Firefox, there appears to absolutely no way to disable it... very nasty way of forcing you to use Chrome?

Moderator note: Edited per OP's request.

I have Firefox set to "ask me every time" what to do with doc and docx files. When I click on one, I get the popup shown in the image. As it shows, for some reason, okular (a pdf viewer) is shown as the pre-selected "open with" option. The dropdown menu also includes LibreOffice Writer, and says (correctly) that this is the default program.

I cannot find any setting on my system where Okular has been associated with doc files. So I think this is a Firefox problem.

How do I remove Okular from this dropdown, or at least make LibreOffice Writer the default pre-selected option?

I have questions about websites I visit that don't seem to work in Firefox, but when I visit the same sites in Microsoft Edge, the sites work fine. Previously (one site, 6 months ago, the second, in the last month), I had no issues with either site. It makes me wonder whether some protocol or requirement has changed that has caused my recent experience. Both sites are secure sites (banking and bill-paying related), and when I first experienced it, I didn't give it much thought since it happened while using the Windows 7 machine. I am now using a newer Windows 11 machine.

My most recent visit to the municipal site (water-bill payment and statement download) resulted in the new tab displaying

HTTP Status 400 - Bad Request

At the credit union site, I click a link that results in rotating arcs atop the webpage's background, and it neither times out nor displays the next screen (a link to a specific account). When I use the credit union's app on my smartphone, the next page displays as it should. (A message reply by the credit union showed a lack of understanding.)

Most of the Firefox settings are at its default settings, and the two sites are allowed to open pop-up tabs.

After 30+ years of using Firefox trouble-free, reverting to Edge is a step backward. (Every time I finish using Edge, I have to run my spyware program.)

Thanks Rapidman

Firefox keeps telling me about a VPN, but I cannot find this or any way to use which corresponds to what I see on the screen. Help says "sign in with a Mozilla account", but I don't know what this means. Sign into what? Looking at the Mozilla site there is no way to register or create an account or tell if I already have one. I've signed up to emails etc but find no difference when I use Firefox. It qualifies - verions and UK - what am I missing?

From the costco login page when I enter my account and password yhe screen dims for a moment but nothing happens. When use the same page from Chrome it works fine.

The Firefox update I was prompted to initiate on May 12 resulted in a compatibility issue message. Following Firebox Help recommendations, I re-installed my Firefox. Now I see that my downloads folder has a long string of unfamiliar files, and I need assurance that these are not remnants of malicious activity. All files have names like i-33639-002-XX.jpg and are dated the same time (5/12/2026, 4:07 PM). Each file shows as “0 KB” in size. All are listed as “JPG File”. Has this happened to other Firefox users?
